Hepatitis A virus (HAV) infection is often a self limiting disease that can be associated with fulminant hepatic failure (FHF). The objective of this study was prevalence of Hepatitis A virus (HAV) on Jeddah population, Saudi Arabia. Also find out the relationship of result with age, gender and ethnicity. For all age groups, there was no significant difference between genders regarding anti–HAV sero positivity. The prevalence of IgG antibodies to HAV was 33.1% overall, 33.6% among males and 32.5% among females with no statistically significant difference (P>0.05). However, it increased significantly with the age. prevalence of Hepatitis A virus by nationality, The IgG antibodies to HAV were found in 20.3 % of Saudi population and 49% of non Saudi population (p0.05). A higher proportion of non–Saudi population were found anti HAV seropositive than Saudi population. There was significant difference between nationalities regarding anti–HAV seropositivity. The prevalence of HAV among adult population (39.3%) was higher than among children population (22.4). The chi–square test showed significant differences in the prevalence of HAV between adult and children population (p0.05).

Food poisoning is a common, yet distressing and sometimes life–threatening problem for millions of people all over the world. More than 250 different diseases can cause food poisoning. Gram''s staining test on these colonies to detect the bacterial type. This step showed that all bacterial samples were gram positive bacteria and confirmed that high degree of similarity between the aerobic and faculatitative aerobic samples in the shape .Six different antibiotics were used to study the resistance of the isolated bacteria against these antibiotics. Different concentrations were used in the culture media starting with 0.005 mg\ml. The MIC was according to the antibiotic activity against the examinated bacteria. The lowest minimum inhibition concentration (MIC) of tetracycline (0.005 mg\ml).then , ampicillin and kanamycin (0.025 mg\ml), then neomycinand spectinomycin (0.08 mg\ml) the highest MIC was in case of chloromphenicol (0.125 mg\ml). This result was confirmed that different degree of antibiotic resistance affecting on the bacterial growth, bacteria have the highest resistance to chloromphenicol and moderate resistance to ampicillin , kanamycin, neomycin and spectinomycin while have the lowest resistance to tetracycline.
